Description

Technical Field

[0001] The invention belongs to the field of medical technology, and in particular relates to an auxiliary compression bed for intravenous pyelography. Background Art

[0002] Intravenous pyelography (IVP) is an important imaging procedure for the clinical diagnosis of urinary system diseases. Through intravenous injection of contrast agent, a compression device is used to temporarily block the downward flow of contrast agent in the ureter, allowing for full visualization of structures such as the renal pelvis and calyces, thereby helping doctors observe the morphology, structure, and pathological conditions of the kidneys, ureters, and bladder. During intravenous pyelography, effective abdominal compression is a key step in obtaining clear images.

[0003] However, most of the existing compression bed auxiliary equipment compresses the patient through a compression belt, and the existing compression belt is often composed of loosening and recycling. Loosening means that after the compression belt is loosened, it is clamped with the bed frame at the other end of the compression bed through a clamping assembly, and then the compression belt is tightened during recycling to complete the compression task. When loosening is required, it is often done by loosening the compression belt. However, when relaxing the compression belt, the entire compression belt is often loosened, which makes the subsequent tightening process more troublesome and is not conducive to replacing the compression belt. Because the compression belt needs to contact the patient's skin, it is easy to cause minor infections.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0035] like Figures 1 to 9As shown, a compression bed for assisting intravenous pyelography includes a compression bed body 1, bed frames 12 are provided on both sides of the compression bed body 1, a support seat 11 is provided at the bottom of the compression bed body 1, a moving mechanism is provided on the two bed frames 12, and a mounting block 2 is provided on the moving mechanism, a mechanical arm body 4 and a protective shell 3 are provided on the two mounting blocks 2, a transmission mechanism is provided in the protective shell 3, and the transmission mechanism is used to drive the mechanical arm body 4 to rotate, and the moving mechanism is used to drive the mounting block 2 to move, the two mechanical arm bodies 4 are symmetrical to each other, and sponge plates 5 are provided at the bottom of the two mechanical arm bodies 4, a locking mechanism is provided between the two sponge plates 5 and the mechanical arm body 4, and the locking mechanism is used to lock the sponge plates 5. The transmission mechanism controls the mechanical arm body 4 to rotate from the bottom to the top of the compression bed body 1, and the cooperation of the mechanical arm body 4 itself can adjust the position of the sponge plate 5, and then control the sponge plate 5 to press down, thereby temporarily blocking the flow of contrast agent in the ureter and bladder to ensure clear visualization of structures such as the renal pelvis and calyces. Because a pressure sensor is provided on the sponge plate 5, the pressure generated during the downward pressure process can be detected at all times.

[0036] In a specific embodiment, the movement mechanism includes two movable chutes 13, each provided on an opposite side wall of the bed frame 12. The two movable chutes 13 are symmetrical to each other. A movable slider 14 is slidably disposed within each of the two movable chutes 13. The two movable sliders 14 are symmetrical to each other. A hydraulic cylinder 15 is disposed on one side wall of each movable slider 14, with the other ends of the two hydraulic cylinders 15 disposed on the inner wall of the movable chutes 13. This arrangement ensures that the operation of the hydraulic cylinders 15 can drive the mounting block 2 to move, thereby enabling the mounting block 2 to drive the movement of the robotic arm body 4, thereby adjusting the position of the robotic arm body 4.

[0037] Furthermore, the opposite side walls of the two mounting blocks 2 are respectively arranged on the movable slider 14, and the two mounting blocks 2 are respectively provided with mounting slots 21 on the side away from the movable slider 14. In this arrangement, the positions of the mounting slots 21 and the connection relationship between the slider 14 and the mounting blocks 2 are determined.

[0038] Furthermore, the transmission mechanism includes two electric motors 31, each mounted on the inner wall of the protective housing 3. A worm 32 is provided at the output end of each electric motor 31, and the other ends of each worm 32 are mounted on the inner wall of the protective housing 3. A worm gear 33 is meshed with each worm 32 above the worm 32. This arrangement ensures the installation position of the transmission mechanism and ensures that the worm gear 33 can rotate.

[0039] Furthermore, a rotating rod 34 is fixedly provided through each of the two worm gears 33. The two rotating rods 34 are movably extended through the protective housing 3 and are fixedly connected to the robot arm body 4. Bearings 35 are provided at both ends of the two rotating rods 34. A fixing block 36 is provided on the side wall opposite the two bearings 35. The two fixing blocks 36 are respectively provided on the mounting block 2. This arrangement ensures that the rotation of the worm gear 33 can also drive the rotation of the rotating rod 34, and thus the rotation of the rotating rod 34 can also drive the rotation of the robot arm body 4.

[0040] Furthermore, the two robot arm bodies 4 are each provided with a rectangular notch 41 at one end away from the mounting block 2. The two opposing walls of the inner cavity of the two rectangular notches 41 are each provided with a placement notch 44. The four placement notches 44 are symmetrical to each other. In this configuration, the positions of the rectangular notches 41 and placement notches 44 are determined.

[0041] Furthermore, the locking mechanism includes four wedge blocks 42, which are symmetrical with each other and are slidably disposed within the inner cavity of the placement slot 44. Return springs 43 are disposed on opposite side walls of each of the four wedge blocks 42, and the other ends of the return springs 43 are disposed on the inner walls of the placement slot 44. The locking mechanism also includes two plug-in blocks 51, which respectively engage with the rectangular slot 41. Each of the two plug-in blocks 51 has two symmetrical limiting slots 52, which engage with the wedge blocks 42 in pairs. A sponge plate 5 is disposed at the bottom of the two plug-in blocks 51. In this arrangement, it is ensured that when the sponge board 5 needs to be replaced, the staff can pull the sponge board 5 downward to make the plug-in block 51 receive a downward force. When the plug-in block 51 is subjected to the downward force, it can give a downward force to the limiting slot 52. When the limiting slot 52 is subjected to the downward force, it can give the inclined surface of the wedge block 42 an extrusion force, so that the wedge block 42 can move into the placement slot 44. Therefore, the sponge board 5 can be taken out from the robot arm body 4 for replacement.

[0042] The implementation principle of the compression bed for intravenous pyelography of the present invention is as follows:

[0043] First, the patient lies on the compression bed body 1;

[0044] At this time, the staff controls the electric motor 31 to operate, so that the electric motor 31 can drive the worm 32 to rotate. When the worm 32 rotates, it can drive the worm wheel 33 to rotate. When the worm wheel 33 rotates, it can drive the rotating rod 34 to rotate (because the rotating rod 34 is fixed and passes through the worm wheel 33). When the rotating rod 34 rotates, it can drive the mechanical arm body 4 to rotate, so that the mechanical arm body 4 is located at the bottom of the compression bed body 1 from its initial position and rotates to the top. At this time, the staff can control the operation of the mechanical arm body 4, so that the mechanical arm body 4 can drive the sponge board 5 to press the solid cotton placed therein (because the control of the mechanical arm body 4 The sponge board 5 is made of solid cotton and is located at the sacral promontory on both sides below the patient's navel in an inverted "eight" shape. A display screen is provided on the sponge board 5 (a pressure sensor is provided on the sponge board 5, and the pressure sensor and the display screen are electrically connected. The pressure sensor is used in a conventional manner). The device is also provided with a display screen for displaying pressure data in real time to ensure accuracy and safety.

[0045] Therefore, the downward pressure of the sponge plate 5 can temporarily block the flow of contrast agent in the ureter and bladder to ensure clear visualization of structures such as the renal pelvis and calyces. When the test is completed, the staff can reverse the above steps to return the robotic arm body 4 to the bottom of the compression bed body 1;

[0046] When the sponge board 5 needs to be replaced, the staff can pull the sponge board 5 downward to make the plug-in block 51 receive a downward force. When the plug-in block 51 is subjected to the downward force, it can give a downward force to the limiting slot 52. When the limiting slot 52 is subjected to the downward force, it can give the inclined surface of the wedge block 42 an extrusion force, so that the wedge block 42 can move into the placement slot 44. Therefore, the sponge board 5 can be taken out from the robot arm body 4 for replacement.
